2040 System Pressures and Velocities <br />A map of the 2040 build -out steady state system pressures calculated by the model, with the tower levels set to the lowest level seen during <br />maximum day demand, is shown in Map 9-6. As with the existing system, under maximum day demand, none of the pipes in the 2040 model <br />indicate velocities greater than 5 fps. The greatest calculated velocities, from 3-5 fps, again occur primarily in the watermain connecting the <br />production wells and water towers to the network. <br />2040 Fire Flow Capacities <br />A map of the 2040 build -out available fire flows, with the tower levels set to the lowest level seen during 2040 maximum day demand, is shown <br />in Map 9-7. The areas that exhibit lower available fire flows in the 2040 model are diminished compared to the existing system, and are still the <br />low density residential areas in the east -central part of the system near Goodview Avenue North. The available flows in this area still satisfy ISO <br />requirements for low density residential development. <br />} <br />2040 COMPREHENSIVE PLAN UPDATE COMPREHENSIVE WATER SUPPLY 223 <br />0-awC <br />AND DISTRIBUITION PLAN <br />
